because they promote the maintenance of healthy weight [42]. UNICEF's nutrition conceptual framework states that caregivers play an important role in promoting healthy diet and participation in physical activity among children.

Parents at home are the model of healthy behavior, so it is important for parents to be educated about healthy foods and the benefits of physical activity so that they can teach their children. Family meals and physical activities in the family are important opportunities to educate children on healthy behavior [42, 43, 46].
